What are the common water meter measurement principles?

The common water meter measurement principles are as follows:

1. Mechanical metering: The water flow drives the internal blades or turbines of the water meter to rotate, and through mechanical structures such as gears and levers, the rotational motion is converted into the movement of the pointer on the dial, thereby measuring the water flow. Whether it is digital or pointer display, users can intuitively read the water consumption.

2. Ultrasonic metering: Using the characteristic that the propagation speed of ultrasonic waves in the fluid is affected by the flow rate, the water flow velocity and pipe diameter are measured non-contactly through the probes at both ends of the pipe to calculate the water volume. It has high precision, strong stability, is not afraid of impurities and bubbles, and has a long service life and is easy to install.

3. Electromagnetic metering: Based on Faraday's law of electromagnetic induction, the water flow cuts the magnetic flux lines to generate electromagnetic signals, and the water volume is calculated based on this. It is also non-contact, simple in structure, strong in anti-interference ability, and performs well under complex working conditions such as high flow rate and high pressure.
